/* -- Log --------------------------------

[2011-03-01 04:21:32] Got it to a somewhat functioning state: it displays HTTP Status, Headers HTML or image, and everything all over again but in hex (coz we're cool kids),
                      badly, if it's funky characters (coz we're not /too/ cool, gotta keep it real, right). curl_get() was copied from online reposithinger but hacked around
a bunch.

Todo:
- Maybe using the PHP class to simulate a browser (http://www.lastcraft.com/browser_documentation.php) could help, here. If not, then at least the method list could serve as
  "inspiration" to re-create something like it closer to what we can use, here. The curl_get() function could be replaced by a class.
- Prevent hitting enter in the URL input to reload the friggin' page, make it run the JS ajax code instead.
- The hex display should filter out more characters that a browser can't display anyway. While there, figure out what the hell is up with that character set converting.
  Right now it won't display unless the characters were first htmlentity'd, THEN iconv'd, char by bloody char. How does that make any sense?
- More hex display: try and see if JavaScript get-selection tricks can be used to colorize the data in one column, based on the selection in the other. The current
  table-row-by-row display will have to change of course.
